Comment on the video card...
I would save for a little more card, such as the Sapphire Radeon 9600se for $78 bucks.
Look at the performance of the MX440 compared to other cards on TomsHardware Guide:
That my pick for a video card fo under $80 bucks.
As for the games...
Counter Strike doesn't require much help from a video card as you know. Condition Zero...don't get it! Spend the money on a better graphic card. All of the improvements in Condition Zero are already in 1.6 that is offered by Steam. Condition Zero = version 1.6 with a couple single player missions.
As for Frozen Throne and BF1942...those are graphic intense games and will run MUCH smoother with a little more beef to your video card. I have a 9800Pro and I still crank up the graphics on BF1942.
